Swapping Logic at Runtime: The Strategy Pattern using First-Class Functions
Beyond Rigid If-Else Logic Traditional approaches to varying behavior use conditional statements scattered throughout code. Need different sorting algorithms? Different pricing strategies? Different attack behaviors in a game? You end up with messy switch statements and tightly coupled code. The Strategy pattern lets you encapsulate algorithms and swap them at runtime. In Go, first-class functions make this pattern beautifully simple—no heavyweight class hierarchies required. The Traditional Approach: Conditionals Everywhere Here’s what happens without the Strategy pattern: ...
